On this week's 'Yoo Hee Yeol's Sketchbook', John Park had the chance to perform and was also interviewed to show his natural goofy side to the audience. The groovy sound of his voice fit naturally well with all the songs he sang on this episode in which he made it sound so easy. As always, he was having fun and feeling comfortable on the stage but also carried out a playful interview for the audience and viewers alike.
